' THOMAS SIMON, OF SAN FRANCISCO, CALIFORNIA.

OIL-BURNER.

T 0 all whom it may concern: 7 Be it known that I, THOMAS SIMON, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to oil burners. An object of the invention is to provide a burner by which any heavy grade of fuel oil may be used with a high degree ofethciency.

It is also an object that the burner can be easily regulated while in operation and any desired shape or size offiame obtained.

It .isa further object that the burner is adapted to be cleaned without dismantling. Other objects, and objects relating to details of construction, combination, and arrangement of parts willhereinafter appear in the detail description tofollow.

i The invention is illustrated by way of example in the accompanying drawings, in

which: I I

. Figure 1 is a central longitudinal sectional view of the burner; Fig. 2 is a vertical cross section on line 2-2of Fig. 1.

Fig. 3 is a forward end view of the burner I nozzle or tip shown in Fig. 1.

Fig-e1- is a'central transverse longitudinal view of a modified form of nozzle.

"Referring to the drawings in detail, 10

indicates a housing which'may be of any desired shape and formed .with one end closedandthe other open; midway its length there is formed a vertically disposed division wall 11, and the compartment formed 'between the wall lland the closed'end of the housing is divided by a horizontally disand 14. The'compartinent 13 is provided 'with an induction pipe 15, and the compart- -ment 14 with'an' induction pipe 16. Also,

posed wall 12, forming the compartments 13 V l the .forward .endIofthe housing is provided with'an' induction pipe, 17 The pipev 16 is connected to 'a source of supply of fuel liquid andv of course has a regulating valve not shown. The pipes 15 and 17 are connected to a steam-or air supply'and a regulating.

valve provided for each] p The open end of'the'housing' is threaded to receivethe threaded end of a casing 18. Within the casing 18 are disposed two pairs of pipes 19 and 20. The pair 19 pass through the wall '11, and communicate with the steam or air compartment Specification of Letters Patent.

Application filed October 5, 1920. Serial No. 414,806.

13. The pair of pipes 20 likewise pass through the wall 11, but communicate with the Oil compartment 14. The pair of pipes .19 are closed at their outer ends by a suitable plug or the like, while the pair of pipes 20 are connected at their enos so that there may be'a continuous passage between them.

The connection between the pair of pipes20 in this instance comprises an extension from one of the pipeswhich terminates in an elbow 21. The elbow is connected to the other.

pipe of the pair by use of a union of which 22 is the female and 23 the male, the male being threaded into a sleeve 23, which is likewise threaded on the pipe :withwhich it is to be connected, Each of the pairs of pipes 19and 20 are provided with a series I of perforations as indicated at24 and these perforations are made of such. a size" which will give the best operative results.

In the drawings therefare two, forms of nozzles shown. The nozzle shown in Fig. 1,

as applied is preferable for many uses of the a burner. The nozzle shown in Fig. 4 may be used in many cases with equal eflicienc'y.

Each form of nozzle is provided with an interlor thread 25 adapted to receive the threaded outer end of the casing.18., The. nozzle shown 1n Fig. 1 comprises acyhndrical portion 26in which the threads 25 are formed, and a wedge shaped forward-pon- 'tion 27. -The interior of thenozzle is di-- vided. by a centrally'disposed wall 28. The forward end ofthe nozzle is provided with two slots 29 and 30. One slot communicates with one nozzle compartment formed by the wall 28 and the other slot communicates with the other compartment. I Also, one slot is preferably made .of greater length than the other.v H I The modified form of nozzle shown in Fig. 4 comprisesa cup-shaped portion 31,

the lower or forward end of which terminates in a pair of. flattened inter spaced members 32 and 33.

a In operation,-the fuel oil enters the chambers and by gravity'or other slight pressure enters the pipes 20 and drips through the perforations 24:. Steam orcompressed a1r enters the chamber 18 .and passes into the In Fig. '1 the atomized fuel.

pipes 19 and from thence into the casing with the oil.

The slot 29 being smaller of course increases the velocity of the atomized fuel passing there through of that passing through the slot 30. The sides of the slot 29 can be inclined in such a manner that the atomized fuel passing therethrough would strike that which is passing through the slot 30, and from the fact that the atomized fuel passing through 29: has a greater velocity, a further atomization of the two streams of fuel would result. Also, the sides of both the slots may be made parallel and cause two parallel streams of atomized fuel to issue. Again, the sides of the slots may be inclined to direct the atomized fuel downward or upward. As is ob vious most any shape or direction of flame can be obtained by theform of nozzle shown in Fig. 1. With the form of nozzle shown .in Fig. 4 only a large fiat flame can be obtained. If desired to direct the flame upward or downward the members 33 and 32 could be bent accordingly.

In connecting the outer ends of the oil pipes 20, a path is afforded and foreign matter or lumps in. the fuel liquid which will not pass through the perforations 24 may pass from one pipe to the other and in this way gradually pulverize themselves and be admitted through the perforations.

In case the fuel is extremely heavy steam may be turned on through the pipe 17. Steam would then be entering the casing 18 through the perforations 24: in the pipes 19 and through the pipe 17. As readily seen, most any fluid fuel of any viscosity or thickness can be used in this manner.

bhould any of the perforations become clogged the same may be cleaned without dismantling the burner by closing the oil pipe 16 and opening both steam pipes 15 and 1'? Any collection of sediment on the pipes or in the perforations is in this manner carried out through the nozzle by the 5 two compartments longitudinally thereof and one of said compartments further divided to form a fuel compartment and an atomizing agent compartment, pipes with aerforations extending from the fuel compartment and atomizing agent compartment into the undivided compartment of the casing, and a nozzle on the end of the casing adjacent the free ends of said pipes.

2. An oil burner comprising a casing having a vertical partition near one end and a horizontal partition by which the separated partition is subdivided into two compartments, steam induction pipes connected with the upper of these compartments and the main compartment, and an oil supply pipe connected with the lower compartment, a plurality of perforated pipes extending from said compartments through tne main casing and a two part nozzle at the end of the casing.

3. In an oil burner, a casing divided into two compartments longitudinally thereof, and one of said compartments further divided to form a fuel compartment and a steam compartment perforated pipes extending from each of said steam and fuel compartments and into the other compartment of the casing, and a nozzle on the end of the casing adjacent the extended ends of the pipes.

a. In an oil burner, a casing divided into two compartments longitudinally thereof,

and one of said compartments further divided to form a fuel compartment and a steam compartment, and a pair of perforated pipes having their outer end closed extending from the steam compartment, said pair of perforated pipes having their outer ends connected and extending fromthe liquid fuel compartment, and a nozzle on the end of the casing adjacent the free ends of said pairs of pipes.

5. In an oil burner a casing divided into two compartments longitudinally thereof and one of said compartments further divided to form a liquid fuel compartment and a steam compartment, pipes with perforatiens extending from the fuel compartment and the steam compartment into the undivided compartment, a steamsupply connection for the steam compartment, a fuel compartment, a steam supply connection for the undivided compartment of the casing, and a nozzle on the end of the casing adjacent the free ends of the pipes. p

In testimony whereof I have hereunto set my hand in thepresence of two subscribing" witnesses.
